The FreeBSD make automatically reads 231541Srgrimes# the /usr/share/mk/sys.mk unless the -m argument is specified on the 241541Srgrimes# command line. By keeping this makefile simple, it doesn't matter too 251541Srgrimes# much how different the installed mk files are from those in the source 261541Srgrimes# tree. This makefile executes a child make process, forcing it to use 271541Srgrimes# the mk files from the source tree which are supposed to DTRT. 281541Srgrimes# 291541Srgrimes# The user-driven targets (as listed above) are implemented in Makefile.inc0 301541Srgrimes# and the private targets are in Makefile.inc1. These are kept separate 311541Srgrimes# to help the bootstrap build from aout to elf format. 321541Srgrimes# 331541Srgrimes# For novices wanting to build from current sources, the simple instructions 341541Srgrimes# are: 351541Srgrimes# 361541Srgrimes# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 371541Srgrimes# 2. `cd /usr/src' (or to the directory containing your source tree). 3814507Shsu# 3. `make world' 3950477Speter# 401541Srgrimes# Be warned, this will update your installed system, except for configuration 411541Srgrimes# files in the /etc directory and for the kernel. You have to do those manually. 422165Spaul# 432165Spaul# If at first you're a little nervous about having a `make world' update 442165Spaul# your system, a `make buildworld' will build everything in the /usr/obj 451541Srgrimes# tree without touching your installed system. To be of any further use 461541Srgrimes# though, a `make installworld' is required. 471541Srgrimes# 481541Srgrimes# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 491541Srgrimes# update the legacy support for aout. This includes all libraries, ld.so 5014507Shsu# and boot objects. This part of build should be regarded as 511541Srgrimes# deprecated and you should _not_ expect to be able to do this past the 5255205Speter# release of 4.0. You have exactly one major release to move entirely 5348726Sphk# to elf. 5448726Sphk# 5548726Sphk# ---------------------------------------------------------------------------- 5648726Sphk# 5748726Sphk# Upgrading an i386 system from a.out to elf format 5810086Sjkh# 591541Srgrimes# 6014507Shsu# The aout->elf transition build is performed by doing a `make upgrade' (or 6114507Shsu# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 6214507Shsu# by a `make aout-to-elf-install', depending on user preference. 6314507Shsu# You need to have at least 320 Mb of free space for the object tree. 6414507Shsu# 6514507Shsu# The upgrade process checks the installed release. If this is 3.0-CURRENT, 6614507Shsu# it is assumed that your kernel contains all the syscalls required by the 6714507Shsu# current sources. 6814507Shsu# 6948726Sphk# The upgrade procedure will stop and ask for confirmation to proceed 7014507Shsu# several times. On each occasion, you can type Ctrl-C to abort the 7114507Shsu# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 7282619Srwatson# the confirmation steps. 731541Srgrimes# 741541Srgrimes# At the end of the upgrade procedure, /etc/objformat is created or 751541Srgrimes# updated to contain OBJFORMAT=elf.
